Kindness and compassion are essential to build trust between patient and provider; It’s what I strive for at every visit.

Dr. Nack works closely with the multidisciplinary oncology team at Regions Hospital to provide each patient with an individualized care plan. She explains complex treatments in an approachable way, helping patients to make personalized decisions regarding their own cancer care.

Dr. Nack is experienced in the most up-to-date radiation technologies, which she utilizes to deliver the optimal dose to target structures while simultaneously sparing healthy, surrounding tissues.

Outside of work, Dr. Nack enjoys skiing, hiking, camping, and spending time with friends and family.
